A great deal of research on second language (L2) input has provided useful linguistic evidence for the development of generalizations about and hypotheses on the usage-based nature of L2 knowledge. However, despite the fact that classrooms are one of the most ubiquitous sites of L2 learning, we still know very little about the linguistic quality…

Background: In this cross-national study, Spanish, Finnish, and Swedish middle and high school students' procedural flexibility was examined, with the specific intent of determining whether and how students' equation-solving accuracy and flexibility varied by country, age, and/or academic track. The 791 student participants were asked to solve…

In many contexts of contemporary ELT, the L2 can be widely encountered beyond the classroom. In these settings, teachers need to maximize opportunities for meaningful participation. Digital video production (DVP) provides one such opportunity. Little, however, is known about the types of DVP common in particular contexts of ELT, the extent to…

Physical education puts the body center stage. Embodiment has emerged as a concept that broadens the focus on the body beyond the dualistic natural scientific point of view. Research into embodied learning and embodiment has had various focuses, including the sociological aspects of embodiment and the embodied experiences of students. This article…

Background: Bringing about conceptual change in school science classrooms is difficult for teachers. Researchers in this field have struggled to influence classroom practice. Purpose: The present research presents a method and a framework for video-based pedagogy analysis. Sample: Six groups of 11-year-old pupils took part (three girls and three…

In K-12 schools, classes are forced to transform online due to the class suspension amid the COVID-19 pandemic. Educators began to design alternative ways to conduct some meaningful learning activities for their students. However, not all subject disciplines could be easily transformed online, especially for those requiring much social interaction…

The purpose of the systematic review of mathematics intervention syntheses was to identify patterns and gaps in content areas, instructional strategies, effect sizes, and definitions of learning disabilities (LD), mathematics LD (MLD), and mathematics difficulty (MD). Using rigorous inclusion criteria, we evaluated 36 syntheses that included 836…

Within the current policy and legislative context of educating students with and without special educational needs (SEN) together in one classroom, the question that is frequently raised by educators relates to how best to implement inclusion and meet the different needs of their students in class. It is also important to understand…

In the field of educational leadership, there is some work around the preferred theories of scholars, but little to no research on how the chosen theories are subsequently applied. Better understanding the purpose, role, and depth of how theory is used in educational leadership can help inform the teaching and mentorship of aspiring leaders and…

The purpose of this study was to develop a multidimensional College Mental Health Assessment Inventory (CMHAI) specifically for the college student population. In the first phase, a conceptual and theoretical review of general existing scales was performed, followed by conducting exploratory semi-structured interviews with twelve participants.…

Integrated science, technology, engineering, and mathematics (iSTEM) education allow learners to utilize multiple disciplinary perspectives. However, the discipline of mathematics remains underrepresented in iSTEM curriculum. To explore the nature of mathematical thinking with an iSTEM curricular approach that emphasizes mathematics, we…

Learning progressions have become an important construct in educational research, in part because of their ability to inform the design of coherent standards, curricula, assessments, and instruction. In this paper, I discuss how a learning progressions approach has guided our development of an early algebra innovation for the elementary grades and…

Isomorphism and homomorphism appear throughout abstract algebra, yet how algebraists characterize these concepts, especially homomorphism, remains understudied. Based on interviews with nine research-active mathematicians, we highlight new sameness-based conceptual metaphors and three new clusters of metaphors: sameness/formal definition, changing…

This study explores a spatial reasoning learning trajectory of a student with difficulty in mathematics. Using a teaching experiment methodology across 15 instructional sessions, we observed how the student responded to instruction based on an established 2D shape composition learning trajectory (Sarama & Clements, 2009). A narrative…

Describing and measuring instructional quality of mathematics lessons is a common goal amongst mathematics education researchers. Such work takes several forms such as classifying and coding instructional moves and student activity or providing high-level rubric-based scores in relation to categories. In this work, we share an innovative mixed…
